This invention relatesto ancveF construction extinguisher" on a' wall"or other-supporting? surfacebut designed to release=the=operatingmechanism for instantaneous use when the extinguisher is removed fromthe mounting means.

Among' the-objects of theinvention is; to proi vide" a; portablefire"extinguisher*which may: be quicltl'y'and easily detached from itswallisupport and operated with one hand;

Another object is to: provide such an ext-in,- gui'sher whiclrwillbeheld in a secure and inoperaable position when mounted on the wallbracket but' which will instantly become operable upon removal from thewall bracket.

Another object is to provide such an extinguisher with a flexible hoseconnection so constructed and arranged that the nozzle at the end of thehose or tube will automatically be raised so that its discharge horn isin substantially a straight line, operative position when theextinguisher is removed from the wall bracket.

A further object is to provide co-acting means on the extinguisher andthe wall bracket support so arranged that the extinguisher cannot beaccidentally operated while supported by the bracket.

Another object is to produce a construction and combination of parts ofmaximum safety, simplicity, efficiency, economy, ease of assembly andoperation, and such further objects, advantages and capabilities as willlater more fully appear and are inherently possessed thereby.

The invention further resides in the construction, combination andarrangement of parts illustrated in the accompanying drawing, and whilethere is shown therein a preferred embodiment, it is to be understoodthat the same is susceptible of modification and change, and comprehendsother details, arrangements of parts, features and constructions withoutdeparting from the spirit of the invention.

In the drawing:

Figure 1 is a fragmentary view in side elevation of the extinguisher andshowing the novel wall bracket for holding the extinguisher insupported, inoperative position.

Figure 2 is a top plan view of the extinguisher showing its manner ofmounting upon a wall or other surface.

Figure 3 is a disassembled view of the extinguisher and mounting withthe extinguisher removed therefrom and ready for instantaneous use.

Referring more particularly to the illustrative embodiment 'shown in thedrawing; a cylinderl for 'contaihing a. fir-e1 extinguishingt substance?such} as carbon' dioxide isshown with? the bottom broken away:Attachedto} the-topof 'cylinder i is a valve body or housing awmcncontains' 'the usual valve assembly: f omontreuing' the discharge of thecontents of the cylindrz At one=-side* of" attacl fed to t-he valve:that when the lever is depressed' the lvalve is opened-and the contents?which has its one end abutting or connected with the housing 2 and itsother end with the horn 4. This spring 1 is under such tension that thetube and spring may be bent upon themselves at substantially a rightangle as shown in Figure 1, but which when released, will automaticallyand instantaneously assume a substantially straight line position asshown in Figure 3.

The bracket 8 for supporting the extinguisher when not in use, isadapted to be fastened to a wall or other supporting surface and has alower pair of supporting lugs 9 and an upper pair of lugs Hi. The lugs 9are so spaced that they span and partially enclose and securely hold theneck of the cylinder 1 just under the housing 2. Bracket 8 is alsoprovided with a side arm or projection Ii so shaped and arranged as togrip and hold in folded position the tube 3, thus affording a secure andcompact arrangement of the parts of the extinguisher when it is not inuse.

tively prevents lever 5 from being depressed and the valve actuated torelease the contents of the cylinder.

It should also be noted that the lugs 9 and i0 I are so spaced andlocated that they hold the substantially rectangular shaped housing andthe extinguisher against rotating movement.

In operation, when the extinguisher is not 1 needed, it remains ininoperative position on the wall with its tube and horn held in compact.lowered position adjacent the cylinder.

When fire breaks out, the operator grasps the extinguisher and pulls itfrom the mounting on the wall. This requires the use 01' but one hand.

The triggerlever is thus released and may be manually depressed asrequired. The spring sup? ported tube 3 tends to automatically andinstantaneously straighten itself when the tube is freleased from itsholder as illustrated in Figure 3,-

straigl' t line andin the same plane as the handle 6, of the triggerlever 5, thus afiording a onehand operated, straight line extinguishercapable of being held in locked and compact positionwhen '15 and theforce of the carbon dioxide rushing through the tube further tends tostraighten the L tube so that when the'extinguisher is in use thehomiand tube are disposed in practically a der when the extinguisher isnot in use.

not;in use but adapted to be immediately availableior operation uponbeing removed from the.

wall supporting means.

Havingthus described my invention, I claim;
